Are planet-killing black holes hiding inside your cat?

Tiny black holes that would drill microscopic tunnels
through matter wouldn't go unnoticed. I think they don't
exist. For that matter, I think black holes, in the sense
of gravitational singularities, don't exist either, for
the simple reason that their mass energy, even though huge,
is not infinite.

If a theory predicts a singularity, this merely tells us

Yes, divide by zero people, but then again,
we do not know the size of an electron.,
so small, so it could be a black hole like thing,
same for some other elementary particles.
If you look at the scale of things, from planets orbiting stars
to electrons orbiting atomic nuclei,
to galaxies orbiting what we call black holes
there could well be a repeating pattern going down-scale so to speak,
also going up-scale multiple universe / big bangs.
We need a mechanism to explain things, and that gives you one.
